How to make a DIY Respirator Using Ecoflex™ 00-35 Silicone and TASK™ 8 Urethane Resin

Multiple PPE respirators can be cast much more quickly than most 3D printers can print them. In this DIY tutorial video, Milo shows how you can quickly mold and cast parts to create a respirator.

A mold is made of a 3D printed respirator using Ecoflex 00-35 fast setting silicone. Ecoflex 00-35 is an extremely soft and stretchable silicone rubber. After demolding, TASK 8 liquid plastic resin is poured into the mold. TASK 8 has a higher heat resistance than other urethane resins, making it suitable to be disinfected at temperatures up to 265F.

A gasket of Ecoflex 00-35 silicone is poured into a 3D printed mold. The gasket is adhered to the resin respirator using Sil-Poxy silicone adhesive to create a proper seal onto the face.
Straps are created using a rubber band or other elastic band. These are attached to the respirator.
A piece of HEPA fabric is inserted into the front of the respirator to complete the respirator.
